Lens cleaners for cameras are not suitable for computer screens,as the coating on glass optics are more durable,use a very soft microfibres cloth,with a few drops of water added.
Also, it's good to clean the microfiber cloths every few weeks, because they can retransfer oils and dust. You can clean microfiber cloths by soaking and rubbing them in hot water and air dry.
Use the microfiber cloth that came with it. Dampen it with warm water, wring it out. Lightly wipe the screen. Don't use any cleaners, paper towels, pressure, etc. The anti-glare coating is very delicate.
